How to draw the Figure 2 in the paper?

[kinredon]

Thank author for your great work. I am wondering how to draw Figure 2 in the paper as shown blow:

I have the following questions about the implementation of Figure 2.

1. All the proposals have been shown in the Figure or only part has been shown.
2. The proposals are before or after NMS?

I hope the authors can give me some advice for representing this figure. Thanks a lot!

Hi, thanks for your questions.

1\ This figure is an overall trend chart to express how the RandBox improve the discriminability between foreground and background. The original figure is densely dots of different colors. We summarized it into such an overall trend chart.
2\ For ORE, we use after nms proposals.

@scuwyh2000 Thanks for your reply.

1. I still wondering what the original figure looks like, there are massive dots with different colors. How do we summarize the original figures into Figure 2 in the paper?
2. "For ORE, we use after nms proposals." Does It mean using after NMS proposals for ORE while before NMS proposals for OW-DETR and RandBox?
